  "abstract": "<p>There are differences in development and composition between the clusters on the vines and the grape berries on the&nbsp;clusters. Therefore, grouping berries by size in wine grape varieties can help better manage the composition of the wine&nbsp;to be produced. The aim of this research is to reveal the effect of berry heterogeneity on primary and secondary metabolites&nbsp;in the cv. Papazkaras\u0131. The Papazkaras\u0131 vines are grafted onto the rootstocks 1103P, 110R, and 420A and are trained in the&nbsp;double Cordon Royat system. The clusters harvested from each rootstock were separated into individual berries. These&nbsp;berries were then grouped by size using sieves. The size groups were: &le;12.00 mm; 12.01-14.00 mm; 14.01-16.00 mm; 16.01-18.00 mm; and &ge;18.00 mm, forming five groups. A control group was created by taking berries from each size group. In terms of primary metabolites in the must, the Papazkaras\u0131/1103P combination and the &ge;18.00 mm size group stood out.&nbsp;However, the maturity indices, Brix, and % alcohol criteria were found to be insufficient for all rootstocks and berry sizes.&nbsp;Regarding secondary metabolites, it was found that the &le;12.00 mm and 12.01-14.00 mm size groups had high values in all graft combinations. The size group with the highest total anthocyanin and total phenolic content was the &le;12.00 mm group.&nbsp;Based on these results, berry size reduction practices will improve quality. The quality of the wines obtained from different&nbsp;size groups should also be supported by sensory analyses. Sorting the berries by size will positively impact grape and thus&nbsp;wine quality.</p>",
